    the angle is five-thirteenth of its complement.
    A 30Ā° Correct Answer Incorrect Answer
    B 40Ā° Correct Answer Incorrect Answer
    C 42Ā° Correct Answer Incorrect Answer
    D 45Ā° Correct Answer Incorrect Answer

    Solution

    Let the angle be 'A'.

    Complement of 'A' = 90Ā° - A

    So, 'A' = (5/13) X (90Ā° - A)

    Or, 13A = 450Ā° - 5A

    Or, 18A = 450Ā°

    Or, 'A' = 25Ā°

    Complement of 'A' = 90Ā° - 25Ā° = 65Ā°

    Required difference = 65Ā° - 25Ā° = 40Ā°

    Hence, option b.
